database connection problem

[thomas.schwarzpaul@xxxxxxxxxxxxxxxxxxx]

Hi all,

i currently upgraded from enhydra 3.1 to enhydra 5.2. Compilation was not the 
problem. But when i start the application, no connection to the database is 
established. I'm using DODS to access data objects.

Here are some of the debug messages:

2005.04.08 13:49:08: HrzShop,DEBUG+ DBConnection[0]:DBConnection[0]: 
jdbc:sapdb://pchrz-trinity/HRZSHOP

2005.04.08 13:49:08: HrzShop,DEBUG+ Connection has been closed.

and so on ...

Even when I try to access data without DODS by using the following connection:

Connection con = getApplication().getDatabaseManager()
                .allocateConnection().getConnection();


no connection is setup.

However when i connect to the database like this:

Class.forName("com.sap.dbtech.jdbc.DriverSapDB");
String url = "jdbc:sapdb://pchrz-trinity/HRZSHOP";
Connection con = DriverManager.getConnection(url,                  
                                        user, passwd);


a connection is established.

Any help is greatly appreciated.
